[Q] Fixing Wi-fi without reformatting?

Hey, in the last few weeks I've run into a very annoying bug on my phone. Wi-fi turns itself off after about 2 minutes. It doesn't actually "turn itself off" in the phone - and by that I mean that the wifi icon is still there, and I can see the signal strength, but the internet won't work.
In order to fix it, I have to turn the wifi off and then on again.
I've tried using the Wifi Fixer application, but it doesn't help. It can't seem to detect when I lose my internet connection.
I've also troubleshooted it, checking that it occurs on different routers/types of networks.
I'm sure it's a problem with my phone, but I dont really want to reformat my phone until Froyo comes (since I don't want to have to install all my apps twice).
Is there any solution to this? ;z
I'm on stock rom, JF3, with OCLF.

I have the same problem with my phone. My Wi-Fi at home works just fine, but when I go to my brother's house, I seem to occasionally lose internet connection even though it shows that it's still connected to the Wi-Fi. I have stock Bell ROM with OCLF by RyanZA. Oh, and to fix it I simply turn Wi-Fi off, and then on, and it starts working again.

Bump :x
Anyone have a solution?

[Q] Router reboots when Captivate reboots?

When I reboot my Captivate, my Rosewill RNX-EasyN4 router reboots also. When the Captivate tries to connect to Wifi that is when the router reboots. This only happens after I reboot the phone. When I just turn off Wifi and then turn it back on, the router is fine. Even if I turn off the Wifi for a while and turn it back later, the router has no problems. Has anyone experienced this problem before? I am running Serendipity 6.3. I think it was happening when I was running stock also, but I am not 100% sure.

Sounds like your router is flakey. Rebooting the Captivate should not cause a reboot of your router. Check the Rosewill website and see if they have updated firmware for your router. That may solve the problem.

I have the latest firmware on the router dated 2010.07.15. I do not think it is a problem with the router because I have multiple notebooks, a PS3, and a wireless printer connected to it. Only the Captivate causes it to reboot.

Turn off wifi before you reboot.

Tried that already. Once I turn Wi-Fi back on, the router reboots.

Ok, try power cycling the router. 2) try the fxr wifi fix from the market.

Tried power cycling already. Installed and ran the FXR Wifi Fix, but that did not help. I went back to try your original suggestion, turn Wi-fi before reboot. Normally I have Flight mode turned on and Wi-fi enabled. When I reboot Wi-fi is disabled. So I assumed that rebooting with Flight mode on was the same as turning Wi-fi off. But I just tried it and they are not the same. When I manually turn off Wi-fi and reboot, it does not cause the router to reboot. The problem seems to be that when I reboot with Wi-fi on the phone is still in the router's WLAN Client Table. And when the phone tries to reconnect while the router thinks the phone is still connected, it causes it to reboot. At least now I can work around it. Thanks for your help.

Are you by any chance using a wireless N router? I've found that my Bionic will reboot my router every time I try to connect, not just on reboots. But if I turn off the wireless N and just use B+G on my router the phone works fine.

Stock, suddenly no wifi.

(5.1.1) I was on wifi at home. I headed out and have been on mobile data for most of the day. I went for a coffee and my wifi won't work. Tried turning the phone off and airplane mode.
When I click Wifi it says it's on with no networks available. I click More settings and it says Turning Wifi on, but doesn't.
I'd rather not reset the phone, any ideas? Thanks.

yea, reboot your phone.

I had that symptom once, while waiting in a doctor's office. Shutting down and booting back up solved it, but this was a few OTA builds ago (i.e., I'm currently stock, lazy me).
Perhaps delete/forget your current WiFi connections and retry?

My connections don't even show up. I'm gonna let the battery run flat and then try... if not, then reset phone.

I let my battery die, my phone turned itself off after about 4% remaining. 10 hours later and when you hit the power button , it shows the low battery warning, but won't turn on.
So, the battery wasn't completely dead. I needed my phone, I plug it in to charge... And WiFi!!!!!!

Just updated to lmy48m... no wifi again. YAY!!! <_<

I'm having this exact problem w/ my WiFi, and I'm now suddenly getting the "!" appearing ever since updating to LMY48M.

i've been having this problem with build LYZ28J & LYZ28K randomly wifi would stop working. i'd reboot my phone and it would work again then it stoped, so i called Tmo got a replacement this time it took a few days and happened again this time i called Google and they called Motorola they had me wipe cache while i was on build LYZ28J and it worked... then i got the LYZ28K update then 3 days later this morning wifi stoped working again. So i figured doing a cache wipe would work again, but it didn't so i backed up everything and booted into recovery and wiped the phone thinking it would work but that did... still shows Wi-Fi toggle off and says turning on Wi-Fi. Called Tmo again they told me to take it to astore anfd get it diagnosed but im going to call google and see whats up. anyone have any luck getting this fixed ?

I'm also having this problem. Stock 5.1.1

Well I get my replacement phone today let's see if this issue happens I'm going to set it up as a new device.

I had the same problem. I've had pretty terrific success disabling Google Connectivity Service, which I think is somehow related to Project Fi. I went into apps, force stop, disable. Since then, I haven't had to reboot my phone. Before that, I was rebooting, toggling airplane mode, etc.
It's not 100% better though. I have had to toggle airplane a few times. But it's been much less frequent than before.

Suddenly happened today, probably the second time ever. No WiFi saved networks, couldn't locate signals, etc.
Rebooted the phone, everything fine again.
Odd.

I can not connect at all to my work's wifi where I have to enter my AD username and password, just can't connect. It worked mostly fine before Andorid 6.0
It is flaky on regular WPA2 wifi too at home, sometimes have to toggle the wifi or even reboot.
Wifi on the Nexus with Android 6.0 is poor to junk basically.

wifi problem

hi,
i installed cm11 and cm12 on my Motorola droid 4 and in both i have the same problem, when i use the wifi sometimes the internet stops in the mobile but the wifi is still connected, when i turn the wifi off and on again it come back. i don't have this issue with cm13 but android 6 is heavy on my mobile. i tried some solutions like delete /data/misc/wifi files and reboot, change wifi advance settings, nothing works.
when i download my apps from the store randomly the internet stops but the wifi keep connected and sometime it come back by it self, but mostly i have to turn on and of the wifi or reconnect again to the network.
also i make factory reset before install the rom, i used these roms (cm-11-20150201-NIGHTLY-maserati.zip, cm-11-20150901-SNAPSHOT-XNG3CAO3G0-maserati.zip and cm-12.1-20160120-NIGHTLY-maserati.zip)
is there any solution for this issue? please help.
thx

Note 5 Wifi Turning On/Off Intermittently

Hi,
My Note 5 (SM--N920W) recently started to switch Wifi, on/off intermittently. Sometimes, the Wifi stays on for 15/20 minutes (like when watching youtube) and some time it turns on/off continuously (mostly, when downloading a large file with a continuous stream of data). I can see that in the phone settings, the Wifi button goes grey (to off position automatically) and turns blue automatically & tries to connect to the router, sometimes it stays connected for some minutes and sometimes it's just instantaneous that it goes grey again (Wifi off). This keeps on repeating.
The phone is updated to Android 7 (official ROM) and has been reset and also tried all different settings like turning off location completely, disabling wifi scanning etc but that didn't help. Any idea what could be wrong? Also, the phone is locked to a carrier for which I don't have the sim anymore. I am not sure if running it without sim is causing this wifi issue.
Thanks! Any help is highly appreciated!

If you can try using a different wireless router or network, and see if the issue persists. I had a similar problem awhile back, except it only happened when Bluetooth was on. I ended up buying a new router instead of the one I was using from Comcast, and it resolved the problem! Also I've similar issues with other devices, and editing the build prop and changing ro.securestorage.support=true to false in /system/build.prop might help.

Thanks a lot for the reply. I'll look into secure storage flag, though it looks like this is for the rooted devices, mine does not seem to be rooted (I bought it online, not sure if that was rooted earlier or not).
Another behavior I have noted, that initially the wifi for first few minutes works ok, no drops or switching on/off. But then it starts to go nuts turning on/off continuously. I am not sure if its a hardware issue, that somehow the wifi module gets hot after a few minutes of usage and starts to malfunction. But I have read somewhere on this forum, that the BT & WIFI are on the same module on the motherboard if the BT runs fine (which it does on my Note5), WIFI as far as hardware is concerned should be OK.
I haven't tried any custom ROM (though tried downgrading to Android 6.1 - ROM from sam mobile) but that didn't work. Any idea, which custom ROM is most stable and easy to apply?
Thanks!

If your on a stock unrooted rom, I'd definitely try another router, even if your just connecting to a friend's. If it doesn't occur then, its the router. As far as custom roms, I'm running the Note fan edition port by RadeonMaya, and it works great.
